community battery

This is not something to recharge the flagging energy of the community, but a battery which solar power producers in the community can share as a storage device.  It is a utility which is large enough to service the storage needs of a number of individual households, and to act as a buffer between them and the grid to prevent sudden power surges in peak production periods alternating with periods of low supply. It makes the whole system more stable.

 While individual battery storage still remains costly, the community facility is very welcome both to the solar power producers and to the organisations responsible for the smooth running of the grid.
